Intel Foreshadow vulnerability

On August 14, 2018, Link Removed more details and mitigation information about a recently identified speculative execution side-channel method called L1 Terminal Fault (L1TF).
L1TF is a speculative execution side channel cache timing vulnerability. In this regard, it is similar to previously reported variants. There are three varieties of L1TF that have been identified. Each variety of L1TF could potentially allow unauthorized disclosure of information residing in the L1 data cache, a small pool of memory within each processor core designed to store information about what the processor core is most likely to do next.
